How to remove Mac Cleaner from Mac?

What is Mac Cleaner?

Mac Cleaner is the name of an application which supposed to clean, protect and optimize Mac computers by removing junk, duplicate files, uninstalling unwanted, unneeded apps, etc. However, it is known that this app is being distributed using questionable methods. Therefore, it is very likely that users who have this app installed on their computers installed in unknowingly, unintentionally. Apps that users download and/or install on such circumstances are categorized as potentially unwanted applications (PUAs).

Mac Cleaner unwanted application

Mac Cleaner has features that allow users to scan heir Mac computer for large and old files, duplicate files, privacy data, installed programs and remove them. However, in order to be able to remove any detected, found files (or other data) users have to activate Mac Cleaner. In other words, they need to pay for its full version. Free version allows to scan systems, but not to perform any further actions. The problem with apps that are categorized as PUAs is that they may be designed to provide fake results - detect fake issues, etc. Apps that perform fake scans do not actually improve computer performance, fix any issues, remove files, etc. Their main purpose is to trick users into believing that there are some things that can be done (in this case improve computer performance) using their features so that users would pay for their activation, registration. It is unknown whether Mac Cleaner performs a fake scan/does not function as it supposed to, however, there is such a possibility. It is worthwhile to mention that it is possible that Mac Cleaner's developers distributed this app together with some other PUA, for example, some browser hijacker and/or an adware-type app. Browser hijackers are programs that are designed to promote fake search engines/their addresses by changing certain browser settings. Adware-type apps are programs that serve advertisements. Both browser hijackers and adware-type apps can be designed to collect browsing-related and/or other sensitive data as well. The problem with data-collecting apps is that collected data could be misused to generate revenue. For instance, it could be sold to third parties (potentially, cyber criminals). Rhis could cause users problems with browsing safety, online privacy, some users may even become victims of identity theft. Therefore, it is advised not to have any PUAs (including Mac Cleaner) installed on browsers and/or computers.

Mac Cleaner is identical to MacMaster and quite similar to many other apps, e.g., Mac Optimizer Pro, MacCleanBooster, Quick Mac Fixer. In most cases such apps are advertised as tools that are designed to clean computers, find and remove malware, fix errors and/or to be useful in some other way. However, quite often they do not function as advertised. Moreover, it is common that users download and/or install such apps unknowingly.

How did potentially unwanted applications install on my computer?

It is common that users download and/or install PUAs through download and/or installation setups of other programs. In other words, together with other programs that they download and/or install intentionally. It happens when PUAs are included in download and installation setups as additional offers. Usually, such offers can be found and declined in their "Custom", "Advanced" or other settings. However, users often leave the aforementioned settings unchanged, which means they give a permission for included PUAs to be downloaded and/or installed too. This distribution method is known as "bundling". Also, sometimes unwanted downloads or installations can be caused by clicking deceptive advertisements that are designed to execute certain scripts.

How to avoid installation of potentially unwanted applications?

Quite often third party downloaders, installers, Peer-to-Peer networks (like eMule, torrent clients), unofficial sites and other similar download, installation channels are used as tools to distribute unwanted software. Therefore, all programs and files should be downloaded from official pages and via direct download links. Download and installation setups that have settings like "Advanced", "Custom" can include offers to download and/or install additional software. For this reason it is advised not to complete downloads and/or installations without checking those settings. Ads that are displayed on questionable pages should never be clicked as well - it is common that such ads are designed to open various untrustworthy, potentially malicious pages. In some cases they cause downloads, installations of unwanted software. All unwanted, suspicious extensions, add-ons and/or plugins that are installed on a web browser should be removed. If there are any programs of this kind installed on the operating system, then they should be uninstalled too. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
